Application filed December 1, L899. SerialNo. 738,812. (ll'o modem To all whom it concern; I

Be it known that I, WILLISLGzgMfiBRAY, a citizen of the United States, residing at Detroit, in the county-of Wayne-and "State of .5 Michigan, have invented certain new and useful Improvements. in Packing-Machines, of which the following-is a sp.eci,fi cation',reference-being had therei' to the-accompanying drawings.

1o The'invention relates topackingmachines, .and has part cular reference to a 'ma'chine'of this type adapted'in use for filling and packing jars or other receptacleswith cheese.

The mvention consists in the peculiar con- 1 struction of the machineand in the novel com-' bination and arrangement of the various parts thereof, 'which'will be more fully here inafterdescribed, and shown in the drawings, in whichi Figure 1 is a perspective view of a machine embodying my invention. Fig, 2 is a vertical central section therethrough. Fig. 3 is a sectional view of the upper portion of the feeding device, the hopper, and a portion of the driving mechanism. Fig. 4 is a detached view of the lock for the clutch and the trip m'echanism therefor, and Fig. 5 is a' detached end view of the yielding stops carried by the drive-shaft.

reference-letter'A designates a frame supported by legs or posts'B, which are adapted to rest on a flooring or platform 0." D designates bracket-arms extend'ing'for- 3 5 ward from the rear portion ofthe frame A' and carrying at their free ends shaft-bearingsE,

in which is journaled a drive-shaft F.

G designates the hopper, supported upon the frame A, which carries at its outer end, and 40 preferably integral therewith,the cover H for the feeding device I. The cover is provided with a vertical tubular bearing J and laterally-projecting slotted lips L, arranged upon each side of the cover, as shown. The feeding device consists, essentially, of

a tapering casing K, the interior of which constitutes the feed-chambenand a worm L. The casing referred to is provided-with bolts M,

to are adapted'to be swung upwardly between shown in Fig. 2.

spout U.

In the drawings thus briefly referred tothe pivotally connected at each side of the casing,

near thetop, to lugs 0. The bolts referred the slotted ears upon the cover and are provided with winged nuts P, which look the casing to thecov'er, as shown.. The worm L is carried by the vertical shaft Q, whichex tends through a b'all'th'rust-bearing R upon the underside of the cover and upwardly through the'tubular'bearingJ. I

-S designatesv a bevel-gear attached'to the I upper end of theshaft, which is adapted to mesh with'a similar gear T upon the driveshaftF. w N

U is a delivery or discharge spout carried by the casing at its lower end.

Beneath the feeding device is arranged a yielding or movable support V in the form of a platform, the latter being supported upon 'avertical shaft W, which extends downward through the flooring of platform (has plainly X designates springs secured tothecrosshead Y upon the lower end of the shaft and connected to the under side of the flooring, as shown, whereby the platform is held normally in close proximity to the delivery- 1 The means for operating or driving the feeding device consists, essentially, of a rotating pulley A, which has motion transmit ted to it in any suitablemanner. This pulley is loosely sleeved upon the drive-shaft F and is thrown into engagement with the shaft by means of a clutch-l3. In construction the clutch consists of the usual collar 0', head D, connected thereto, and laterally-extending pins E, carried by the h6td.- 1 These pins are adapted to project through apertures F] in the hub of the pulley and to be thrown into the path of yielding stops G',which are securedto and carried by a collar II upon the end of the drive-shaft. A lever J, fixed to a stub-shaft K,engages the collar 0 of the clutch through its bifurcated end L. The stub-shaft has bearings in the bracket M on the frame and It will readily be seen from. the description charged through said casing by means of the worm into a receptacle, such as 13 which is adapted to rest upon the yieldingor movable support immediately beneath the dischargespout U. As the receptacle, which is preferably in'theform of a jar, fills the movable support recedes from the delivery-spout, so

that the jar is entirely filled and packed. I

have provided means whereby after the packing of the jar has been efiected the operation of the feeding mechanism will be stopped to allow of the jar being removed and another substituted in its place. The construction of this mechanism is as follows:

a and b designate bracket-arms extending inwardly from one of the supporting-legs, and

fixedly secured to these laterally extending brackets are guide-rods c. (l is a slide which engages thesc rods for vertical movement, and

e is the slide-rod, which extends upwardly through the frame and also through the end hf the operating-lever, as plainly shown in Fig. 2. At its extreme upper end the sliding rod is provided with a wing-nut f, and interposed between this nut and the operating-lever is a spring 9.

h designates a second spring of less tension than the spring 9, which connects the operating-lever with one of the bracket-arms D.- Q designates a hook pivoted toone of'the bracket-arms referred to in the vertical plane of movement of the operating-lever and is adapted to engage and lock said lever when the latter is in its extreme upward position. '5 designates a spring acting normally to hold the hook beneath the operating-lever, and j is a chain attached to a lug or arm upon the hook, which extends downwardly through the platform 0 and carries at its nd a rod R. The rod referred to has a vertical sliding en-- gagement with a lateral arm S, carried by and fixed to the supporting-rod W.

T designates a nut adjustably arranged upon thefree end of the rod R,

The operating -'lever is normally held through the agency of the spriugg in its lowest position, the drive-pulley being disconnected from the shaft.

When it is desired to start the machine in operation, the slide d isenoved upwardly upon the guide-rods, which releases the tension upon the spring g A ing or pin a upon the slide-rod strikes beneath the operatinglever and raises the same with the assistance of the spring h until it engages the hook Q, The spring 9 is then compressed by returning the slide to its initial position and is held under tension by locking the llslideto the guide-frame by means of a pivoted hook a. This movementof the lever starts the feeding device in operation. As the jar is filled the receding movement of the movable-support V causes the arm S to strike against the head or nut T, which trips the hook Q.

The said lever is returned to its normal position by the spring 9 and disengages the drive-pulley from the drive-shaft for the feed.

lVhat I claim as my invention is 1. In a packing-machine, the combination of the feeding device and a driving mechanism therefor, a lever controlling the operation of the feeding device, a spring acting normally upon the leve 1:,..means for moving said lever into an operative position, a hook for holding the lever in said position, means for compressing the spring after the locking of the lever has been efieet'ed, a movable suptrip operated by the support. v
